Well, now: Isn't that strange? That happens to be exactly what I do own.
(Among other things, of course.)

Why?
One backs-up the other: Replacement gun, parts-gun, wife's "serious social encounter" pistol.
Both guns use the exact same holsters.
Both guns use the exact same magazines.
Both guns use the exact same spare parts.
Both guns use the exact same ammunition.

Glock 19 - availability of 9mm ammo, size, concealability, reliability, and after market parts plentiful.
Ruger SB .44 magnum - do-all caliber, from target to big game, and able to be used at farily long range....150 yards or better.

Have to like Steve's idea of 1911 x2 for all the reasons he gave. But since we're mostly talking about two different pistols one would be my Glock 19 and the other would be a Kimber 1911 just 'cause I want one.

Reason? Getting food may end up as important as defense. Nothing I can't kill to eat with these two. Anything the .357 can't kill is too big to p*** off, much less try to eat! The Ruger MKII would probably end up being the most important gun to have.
